Scalable micro/nanostructured superhydrophobic surface modifications for enhanced energy efficiency and heat transfer performance in stainless steel and titanium

Condensation refers to the change of a substance from a gaseous phase to a liquid phase, an example of which is the condensation of water vapor in nature. Condensation is used in many industries, such as energy generation and seawater desal...

Arctic cloud condensation nuclei enhanced by iodine, sulfur and organic precursors.

Reentrant condensation of a multicomponent cola/milk system induced by polyphosphate

Reentrant condensation (RC) is a protein behavior in which the protein solution shifts between the one- and two-phase state more than twice by increasing a single parameter. Although RC would be a candidate mechanism for the physicochemical...

Influence of Non - Condensable Gases on the Processes of Heat and Mass Transfer during Film Condensation of Steam in Heat Exchangers

The aim of the article is a quantitative assessment of the influence of non-condensable gases on the intensity of heat and mass transfer processes during film condensation of steam in the specific conditions for heat exchanger. The task is ...

External Thermal Insulation Composite Systems: Critical Parameters for Surface Hygrothermal Behaviour

External Thermal Insulation Composite Systems (ETICS) are often used in Europe. Despite its thermal advantages, low cost, and ease of application, this system has serious problems of biological growth causing the cladding defacement. Recent...

Environmentally friendly magnesium potassium phosphate cement-based coating with high anti-corrosion performance on iron

Magnesium potassium phosphate cement-based (MKPC) coating is regarded as an attractive green coating that improves the corrosion resistance of metals. Unfortunately, practical use remains challenging owing to the rapid solidification and ha...

Pyrolysis and Pyrolysis Reoxidation Combustion Characteristics of Lignite

Coal, as the main energy source for building heating in northern cities of China, features large reserves, low cost, and high stability in heat supply. Low-temperature pyrolysis reactions are prone to occur within the coal pile; the coal af...

Effect of Contamination with Impression Materials on Shear Bond Strength of Porcelain to Immediately Sealed Dentin

Objective:  The aim of the present study was to evaluate the effect of two impression materials on the shear bond strength of porcelain to immediately sealed dentin. Materials and Methods: Smooth dentin surfaces of 45 extracted premolar...

Perceptions of cervical cancer prevention among a group of ethnic minority women in Denmark-A qualitative study.

BackgroundCervical cancer screening (CCS) and human papillomavirus vaccination (HPVV) are effective measures against cervical cancer (CC). Attendance in HPVV and CCS provides the greatest protection, while combined non-attendance in HPVV an...

Problem-Based Learning Approach to Review the Principles of Green Chemistry Applied to a Polycondensation Reaction

Science Education International ¦ Volume 32 ¦ Issue 2 107 ORIGINAL ARTICLE INTRODUCTION The problem-based learning (PBL) methodology is a student-centered approach that is related to the learning process that occurs when students deal w...

Laboratorul de cercetare şi încercări higrotermice, instrument de verificare experimentală a calităţii construcţiilor, echipamentelor şi gestionării eficiente a energiei

This paper seeks to present the technical conditions and the main types of research and experimental verifications being conducted by the Laboratory of Research and Hygrothermal Testing for Materials, Building Elements and Parts at INCD URB...

Hybrid Organometallic-Inorganic Nanomaterial: Acetyl Ferrocene Schiff base Immobilized on Silica Coated Magnetite Nanoparticles

In  this  work,  a  new  hybrid  organometallic-inorganic  hybrid nanomaterial was prepared by immobilization of acetyl ferrocene on the  surface  of magnetite  nanoparticles. Covalent  grafting of silica coated magnetite nanoparticles (SCM...

Impact of Urbanization on Cloud Characteristics over Sofia, Bulgaria

Urban artificial surfaces and structures induce modifications in land–atmosphere interactions, affecting the exchange of energy, momentum, and substances. These modifications stimulate urban climate formation by altering the values and dyna...

Series Solution for Steady Three-Dimensional Flow due to Spraying on Inclined Spinning Disk by Homotopy Perturbation Method

The steady three-dimensional flow of condensation or spraying on inclined spinning disk is studied analytically. The governing nonlinear equations and their associated boundary conditions are transformed into the system of nonlinear ordinar...

I do not want to suppress the natural process of inflammation: new insights on factors associated with non-adherence in rheumatoid arthritis

Abstract Background It is estimated that 50–70% of patients with rheumatoid arthritis (RA) are non-adherent to their recommended treatment. Non-adherent patients have a higher risk of not reaching an optimal clinical outcome. We explored fa...

RETRACTED ARTICLE: Defective DNA repair and chromatin organization in patients with quiescent systemic lupus erythematosus

Abstract Background Excessive autoantibody production characterizing systemic lupus erythematosus (SLE) occurs irrespective of the disease’s clinical status and is linked to increased lymphocyte apoptosis. Herein, we tested the hypothesis t...
